Removing phy2phy_tput_mod_vlan test case execution from daily job

This patch is used to remove phy2phy_tput_mod_vlan packet forwarding
test case execution from kvmfornfv daily job as this test case has no
guest involved.

Kvmfornfv will execute only test cases that involves atleast one or more
guests.

Note: phy2phy_tput test case is an exception and will be used in future
for comparing results and debugging if needed.
